provements in Stop and Vaste Cocks; and we.

do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- 'pertains to make and use the same, reference bein g had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in stop and waste cocks, our obj ect being to provide a device of this character which shall be simple in construction, economical in cost, reliable, durable, and efficient in use; and -to these ends the invention consists of the features hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical longitudinal section taken through ourimproved construction. Fig. 2 is a section taken on the line w, Fig. 1, looking in the direction of the arrow. Fig. 3 is a section taken on .the line 'w w, Figs. 1 and 2. Fig. 4. is a section taken on the line y y, Fig. 2. Figs. 5 and 6 are fragmentary views illustrating the course of the waste or drainage water.

Similar reference characters indicating corresponding parts in the views, let the numeral 5 designate a casing provided with a downward swell or projection 5f, located between the two parts 5b and 5C of the main chamber of the casing, but in a lower plane. The center of the casing above this projection is bored out and tapped to receive a screwplug 6, which is provided with a cap' 6a. Through a suitable opening formed in this plug is inserted a stem 7, which is provided with a threaded portion engaging threads formed in the plug. The threads of the stem are coarse to make the movement'rapid in opening and closing the valve. To the lower extremity of the stem is attached a valve 8, which, as shown in the drawings, has the shape of a sli ghtly-elongated ball. The opening 9 in the casing below the plug 6 will be termed the valve-chamber. In this chamber is located a disk .10, provided with an opening through which the stem passes. This disk rests on a ledge or shoulder 12, surrounding the central portion of the valve-chamber. In the lower surface of this disk is formed a concave seat 10fb for the upper portion of the valve. In the bottom of the projection 5 of the casing is formed a seat 13 for the lower portion of the valve, which is adapted to vibrate between these two seats. The under surface of the disk 10 engages a washer 14, while between the plug 6 and the disk is located awasher 15. The plug is screwed down tight on the disk and holds the latter securely in place.

The compartments 5? and 5o of the casingchamber communicate with each other by way' of two channels A and B, formed in the projection 5a of the casing. These channels occupy different planes, one being located above the other. They communicate with each other by means of an opening C, surrounded by the valve-seat 13. Hence when the valve occupies its lower seat communication between the parts 5b and 5C of the casing-chamber is cut off, while when the valve occupies its higher seat the water passes freely from one channel to the other.

The valve-stem is cut away on two opposite sides, vas shown at 7 a, to permit the waste or drainage water.

When our improved construction is in use, the normal position of the valve 8 is that shown in Figs. 3 and 4, allowing the water to pass freely from the compartment 5b to the compartment 5c on its way through the pipes of the system. When for any reason it is desired to cut 0H the water for the purpose of draining the pipes in the house, the stem 7 is turned sufficiently to move the valve 8 downward to its seat 13, thus cutting off communication between the compartments 5b and IOO 5c and allowing the Waste water from above in the system to pass through the compartment 5C and thence upward through the valvechaniber above the valve, thence through the opening in the disk l0, around the part- '7AfL of the stem to the circular recess 16, thence by way of the channels 17 to the groove 18, and thence out of the discharge-spout 19.

Having thus described our invention, what we claim is 1. The combination with a stop and waste cock, of a casing having a projection extending below its body portion, the casing being bored above to form a chamber, a plug screwed into said chamber, a valve-chamber being formed below the plug, a stem passed through the plug and projecting into the valve-chamber, a valve attached to said stem which is provided Witha screw-thread engaging threads in the plug, a main passage for the Water being formed below the Valve, and a wastepassage above the valve, two seats being formed between which the valve is adapted to vibrate, the arrangement being such that when the valve engages the lower seat, the main water-passage is closed and the waste-passage open, while when the valve e11- gages the upper seat, the main vpassage is open and the waste-passage closed.

2. In a stop and waste cock, the combination of a casing inclosing a valve-chamber connected with the main waterway, a Wasteway being formed leading from said chamber, a screw-stem projecting into the valvechamber, a valve attached to said stem, two seats being provided at the extremities of the valve-chamber between which the valve is adapted to vibrate according as its screwstem is turned in the one direction or the other, the arrangement being such that when the valve engages one seat, the main passage is closed and the Waste-passage opened, and when the valve engages the other seat, the main passage is opened and the waste-passage closed.

In testimony whereof we afiix our signatures in presence of two witnesses.
